superio: Don't use MAX_SERIAL_PORTS for serial port limit
The superio device has a limit on the number of serial ports it supports which is really only there because it has a fixed-size array serial[]. This limit isn't related particularly to the global MAX_SERIAL_PORTS limit, so use a different #define for it. (In practice the users of superio only ever want 2 serial ports.)
